a man was brought to the Prophet for him to offer the funeral prayer, and he said: "Pray for your companion, for he owes a debt." Abu Qatadah said: " I will pay it." The Prophet said: "In full?" He said: "In full." So he prayed for him (Using translation from Nasāʾī 1960)
أَنَّ رَسُولَ اللهِ ﷺ أُتِيَ بِرَجُلٍ مِنَ الْأَنْصَارِ لِيُصَلِّيَ عَلَيْهِ فَقَالَ النَّبِيُّ ﷺ «صَلُّوا عَلَى صَاحِبِكُمْ فَإِنَّ عَلَيْهِ دَيْنًا» قَالَ أَبُو قَتَادَةَ هُوَ عَلَيَّ فَقَالَ النَّبِيُّ ﷺ بِالْوَفَاءِ قَالَ بِالْوَفَاءِ قَالَ فَصَلَّى عَلَيْهِ
